PIAA 510 is a direct replacement for the lights, whick are actually round even though the cutout is oval. I just put in a set of PIAA 1000 series oval lights and they are PERFECT!! They fit just inside the stock opening and work great. I did not use the 510's because the stock cutout blosked part of the lens. Hope this helps.
